If the impulse assembly isnt working THERES NO WORRY ABOUT HAND CRANK STARTING BECAUSE AT SUCH SLOW CRANKING SPEED THERES NOT GONNA BE SUFFICIENT SPARK.
The reason why its needed on magneto equipped hand start tractors is because theres practically no spark energy created when cranking soooooooo slowwwwwwwwww... Sooooooo what it does is wind up then trip a spring so the magnetic rotor spins fast past the coil SO THERE IS A GOOD SPARK. Then once running over 250 RPM the assembly drops out altogether i.e. no more spring wind up and tripping.....
When the impulse assembly is working the static start timing is 20 to 30 degrees lagging from the run time advance, i.e. she fires right near TDC so theres no kickback. Again if its not working (no spring wind up and trip) then theres NOT gonna be any spark at the wrong time to worry about
